3 things I noticed....1: He's riding alone in terrain like that which is kinda stupid....2:just before he gets to the top he damn near whacked a tree on his right....3: He was actually slowing because he knew what was ahead, but a drift to his left lurches the sled right, into another one which shoots him back to the left....and that's why he damn near went over.
Between cars, 4x4's, dirt bikes, and street bikes, (and crazy women) I have scared the shit out of myself a million times....and mostly because I love the fear-factor.....but this video blew my damn mind!!
